[I] [Bug] When configuring condition route to route traffic to particular instance, there is still traffic in others [dubbo]
jk-tonycui opened a new issue, #16130:
URL: https://github.com/apache/dubbo/issues/16130
### Pre-check
- [x] I am sure that all the content I provide is in English.
### Search before asking
- [x] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar issues.
### Apache Dubbo Component
Java SDK (apache/dubbo)
### Dubbo Version
Dubbo 3.3.6, JDK 1.8
### Steps to reproduce this issue
When configuring condition route to route traffic to particular instance, there is still traffic in others
### What you expected to happen
The route config should be executed exactly. When configuration is set, traffic should follow the configuration to route traffic to the specified instance.
### Anything else
After debugging, the root cause is the code below in `AbstractStateRouter`
```
routeResult = doRoute(invokers, url, invocation, needToPrintMessage, nodeHolder, messageHolder);
if (routeResult != invokers) {
routeResult = invokers.and(routeResult);
}
```
`invokers.and` should only return the invokes that contains in both lists, but the implementation of and function is adding the tailList together. Therefore ,the final routeResults are redundant.
### Do you have a (mini) reproduction demo?
- [ ] Yes, I have a minimal reproduction demo to help resolve this issue more effectively!
### Are you willing to submit a pull request to fix on your own?
- [x] Yes I am willing to submit a pull request on my own!
